The 125A rating makes this fuse appropriate for protecting cable runs and equipment on 12V, 24V, and 48V systems where sustained high currents are expected. The 80V DC voltage rating provides adequate headroom for 48V battery systems, including lithium battery banks that may reach higher charge voltages.\u003c\/p\u003e\n\n\u003cp\u003eThe fuse acts as the last line of protection against wiring faults and short circuits. Correct fuse selection is critical: the fuse should be rated to protect the cable, not the load. A 125A fuse is typically paired with cable capable of carrying that current continuously, and should be installed as close to the positive terminal of the battery as practically possible to minimise unprotected cable length.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: CIP138125020\u003c\/li\u003e\n  \u003cli\u003eCurrent rating: 125A\u003c\/li\u003e\n  \u003cli\u003eVoltage rating: 80V DC\u003c\/li\u003e\n  \u003cli\u003eFuse type: MEGA blade fuse\u003c\/li\u003e\n  \u003cli\u003ePack quantity: 5 pieces\u003c\/li\u003e\n  \u003cli\u003eWeight: 0.045 kg (per pack)\u003c\/li\u003e\n  \u003cli\u003eGTIN: 8719076061670\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOvercurrent protection between battery banks and inverters or inverter\/chargers on 12V, 24V, and 48V systems.\u003c\/li\u003e\n  \u003cli\u003eDC distribution boards and busbar protection in off-grid and marine installations.\u003c\/li\u003e\n  \u003cli\u003eProtection of high-current DC cable runs in motorhome, caravan, and commercial vehicle builds.\u003c\/li\u003e\n  \u003cli\u003eReplacement fusing in existing MEGA fuseholder installations during service or upgrade work.\u003c\/li\u003e\n  \u003cli\u003eMulti-circuit DC protection in solar off-grid systems with high battery discharge currents.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e5 x Victron Energy MEGA-fuse 125A\/80V\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eMEGA-fuses must be installed in a compatible MEGA fuseholder rated for the current and voltage of the application. The fuse should be positioned as close to the battery positive terminal as possible to protect the full length of the cable run. DC electrical work on battery systems, particularly those involving inverters or lithium battery banks, should be carried out by a qualified electrician or accredited installer. Always verify that the cable cross-section is correctly matched to the fuse rating before installation.\u003c\/p\u003e","brand":"Victron Energy","offers":[{"title":"Default Title","offer_id":50670165164366,"sku":"CIP138125020","price":28.88,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/3698\/8238\/files\/victron-energy-125-amp-80-volt-mega-fuse-CIP138125020copy.jpg?v=1747948492","url":"https:\/\/voltaconsolar.com\/products\/victron-mega-fuse-125a-80v-pack-5","provider":"VoltaconSolar","version":"1.0","type":"link"}
